Please forgive this comment about my own product, but the message above
could leave an incorrect impression.
An 'instant-on' tube doesn't need the warm-up timer on my board, but it
does benefit from all the other metering and protection features.
The manual actually deals with this point: for 'instant-on' tubes, the
warm-up delay can be eliminated by changing two components.
